What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests RadProtect® in healthy volunteers to ensure it is safe and well-tolerated. The main goal is to observe side effects and determine safe dosage levels.

Do I have to stop taking my current medications for the RadProtect trial?

The trial protocol does not specify if you must stop taking your current medications, but you must agree to abstain from taking unauthorized medications or supplements during the trial.

How does the RadProtect treatment differ from other radiation protection treatments?

RadProtect is unique because it is designed to protect against radiation injury when given before exposure, allowing for higher radiation doses in cancer treatment with less damage to normal tissues. This makes it different from other treatments that may only mitigate damage after exposure. ^{1 2 3 4 5}

What data supports the effectiveness of the drug RadProtect® for radiation protection?

Research shows that combining radioprotective agents can be more effective than using them individually, suggesting that RadProtect® might work well when used with other treatments. Additionally, radioprotectors can help protect normal tissues from radiation damage, potentially improving outcomes in cancer treatment. ^{1 6 7 8 9}

Are You a Good Fit for This Trial?

Healthy adults aged 18-64 with normal blood pressure and BMI of 18-30 kg/m^2 can join. They must not have diabetes, heart, liver, or kidney diseases, active cancer, or certain other conditions. Participants need to use reliable contraception and avoid other trials or experimental treatments.

What Are the Treatments Tested in This Trial?

Interventions

• RadProtect®

Trial Overview The trial is testing RadProtect®, a new drug for preventing radiation injury. It's an early-stage study where volunteers receive increasing doses to check the drug's safety and how it moves through the body over time.

How Is the Trial Designed?

Group I: RadProtect® Experimental Treatment 1 Intervention

RadProtect® is not a full-closed micelle, and uses ferrous iron to provide linkage between PEG-b-PGA and amifostine. Transferrin and other related proteins can chelate with ferrous iron and break the micelle releasing amifostine into the blood stream.

Published Research Related to This Trial

In a study involving 137 patients undergoing coronary angiography and percutaneous coronary intervention, the use of RADPAD significantly reduced radiation exposure for the primary operator (PO) compared to procedures without it, with reductions in dose relative to various measures (CAST, DAP, and AK).

The findings also indicated that secondary operators (SO) experienced similar reductions in radiation exposure when RADPAD was used, highlighting its effectiveness in enhancing safety during fluoroscopic procedures.

Minimizing scattered radiation dose in cardiac catheterization laboratory during interventional procedures using lead free drape - MILD study. Bhat, KG., Guleria, VS., Singla, M., et al.[2022]

The RADPAD surgical drape significantly reduces radiation exposure to primary operators during routine diagnostic coronary angiography, with a 59% reduction in total radiation exposure and a 47% reduction in the radiation exposure rate.

In a study involving 60 patients, the primary operator's radiation dose was significantly lower when using the RADPAD (8.0 µSv) compared to the control group (19.6 µSv), indicating its efficacy in protecting healthcare staff from ionizing radiation.

Efficacy of RADPAD protective drape during coronary angiography. Kherad, B., Jerichow, T., Blaschke, F., et al.[2019]

In a randomized study of 60 patients undergoing coronary angiography, the use of the Radpad radiation shield significantly reduced the operator's radiation exposure by 23%, despite similar procedure times and total examination doses.

The Radpad shield provided consistent reductions in radiation exposure across various body locations, ranging from 13% to 34%, highlighting its effectiveness in protecting healthcare workers during interventional procedures.
